WATER HEATER.

. Application filed June 12,

It is the object of the invention to provide asimple and economically constructed device for heating water by means of electricity.

It is another object of the invention to provide a device of the character indicated that is rendered operative or inoperative by insertion in Water or removal therefrom as the casemay be.

In the drawing Figure 1 is a longitudinal sectional view of the device, partly in elevation.

Figure 2 is a sectional view on line of Figure 1.

Figure 3 is a sectional view on line cl- 3 of Figure 1.

Referring more particularly to the draw ing, I show at 1 a tubular element provided with any suitable number oi orifices as at 2 and having a suitable electricity insulating material such as rubber inserted in one end thereof as shown at 3.

At t I show a closure for the other end oi? the tube this closure being removably inserted therein and formed of a suitable insulating material and extending a distance beyond the end of the tube when inserted therein. Secured to the inner surface of this closure by means of bolts 5 are apair 0t semi-circular hard-lead discs 6 and 7, spaced a distance apart as shown at 8.

To the disc 6 are secured a pair of spaced plates 9 by means of a connecting neck 10, and to the disc 7 are secured a similar pair of spaced plates 11 by means of neck portions 12. These plates 9 and 11 are of equal width and lie in spaced parallel relation to each other as clearly shown in Figure 1. The lower ends of the plates are held in the desired spaced relation by annular discs o'l rubber or other suitable insulation material as shown at 13, the central disc being larger in diameter than the two side discs, and all being proportioned to engage the inner walls of the tube 1. A pin 14 is passed through the plates and the centers of the several discs to hold them in position, and this pin preferably extends a distance beyond the sides of the plates to engage the walls of the tube 1 and assist in holding the plates in spaced relation thereto.

At 15 is a binding post mounted on the outer surface of closure A by means of a pin extending therethrough and engaging the disc 6 and having a wire 16 mounted therein as shown. At 17 is a second binding post 1925. Serial NO. 115.568.

mounted on the closure 1 by means of a pin engaging disc 7 and titted with a wire 18.

A short tubular section shown at 19 lined with an asbestos insulation 20 and adapted to lit over the upper portion of the closure 4. This tube 19 is litted with an insulating plug 21 to which a porcelain cap is secured by bolts 22, the wires 1618 passing therethrough as shown.

The parts 1 and 19 join over the closure 4 at 25. so that when the device is assembled as described it presents the appearance of being merely a perforated tube with a porcelain end piece.

The wires 16-18 being properly connected in an electrical circuit by means of a plug or any other suitable device not shown, it is ready for use. There is no electrical current. timring before immersion in water because there is no conductor between the several plates. Vv' hen, however, the device is immersed in water the water enters tube 1 through orifices 2 and encompasses the several plates. Water being a good conductor of electricity it now opens up a path of travel between the several plates so that the current may tlow freely through one terminal as 15 to the connecting disc 6 and the plates 9-9 carried thereby, thence through the water to the plates 11-11, disc 7 and terminal 17 to the wire 18. The heat generated by the flowing electrical current rapidly heals the water as desired. v

A device constructed after the manner set forth may be generally used without the provision of a mechanical switch of any kind because when removed from the water the device is inoperative and can only be rendered operative by effecting a proper connection between the several plates. This connection can only be etl'ectually made by introducing a liquid into the tube 1. i

This device is economical to manufacture and has a long and etlicient life because there are no small wire coils or other delicate parts to burn out quickly.

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes in form, construction and method of operation may be made within the scope ol the appended claim.

I claim An article of manufacture comprising a tubular element provided with means to permit the flow of Water therethrough, an insulating closure for one end thereof, spaced conducting plates mounted on said closure and extending into said tube, insulating means inserted between the ends of said plates remote from said closure to space the same and engaging the wall 01 said tube, and

lying in parallel relation to said plates a pin passing throu h said plates and msulatin means and engaging the Wall of said tube, means for connecting said plates in an electrical circuit, and an insulated cap mounted on said tube over said closure.
